Abstract (en)

In an example, a User Equipment, UE, operates with shared spectrum channel access on a carrier and/or a cell. The UE receives a configuration for configuring configured grants for uplink transmission in a bandwidth part, BWP, (2005). The configured grants include a first configured grant and a second configured grant. The UE configures a first minimum Downlink Feedback Indication, DFI, time delay for the first configured grant according to the configuration (2010). The first minimum DFI time delay is for validation of Hybrid Automatic Repeat Request, HARQ, information in response to one or more first uplink transmissions. The UE configures a second minimum DFI time delay for the second configured grant according to the configuration (2015). The second minimum DFI time delay is for validation of HARQ information in response to one or more second uplink transmissions. The UE does not expect the second minimum DFI time delay to have a different value than the first minimum DFI time delay.
